- This paper deals with the investigation of structural and absorption properties of microwave dielectric ceramics with the general formula Ba 6-3x R 8+2x Ti 18 O 54 where R = La, Sm and x = 2/3. The X-ray diffraction analysis revealed tungsten bronze type crystal structure with orthorhombic symmetry for these ceramics. The scanning electron micrograph shows uniform needle like elongated grains. Absorption properties i.e. absorption loss, return loss and insertion loss have been measured for the synthesised samples with respect to the frequency in the range 8.0 GHz-12.0 GHz at room temperature.
